Short diagnostic hints for the two Practice on your own problems in this chapter. Attempt each problem before opening the hint. Complete answers appear in Appendix G of The Defensible Decision: Practice Workbook.
Problem 1 — the operational-monitoring exception
Restated: A logistics team asks Copilot for a real-time warehouse-throughput dashboard. Copilot returns a 12-visual page, dense and detailed. Name why the 5-Visual Rule may not be the right check for this dashboard, and name the check that replaces it for the operational-monitoring case.
Show a diagnostic hint
Diagnostic cue. Decide whether this is an exception-monitoring task or a decision page, then design for the reader's next action.
Complete answers appear in Appendix G of The Defensible Decision: Practice Workbook.
Problem 2 — the blurred-thumbnail failure
Restated: You take a screenshot of a dashboard, blur it, and it reads as uniform noise (no primary visible, no cluster, no white space). Which two of the four Refine checks are most likely failing? Name the sequence you would apply to fix the failure.
Show a diagnostic hint
Diagnostic cue. Test the dashboard at its actual consumption size before declaring hierarchy successful.

About the three-tier Practice format
Each chapter of the book closes with a three-tier Practice block adapted from Cole Nussbaumer Knaflic’s course-adoption pattern in Storytelling with Data: Let’s Practice!: Practice with us (one worked problem with full solution in the book), Practice on your own (open problems with complete answers in Appendix G of the Practice Workbook; this page offers short diagnostic hints), and Practice at work (an open-ended prompt to apply the chapter’s move to a live artifact). This page hosts the middle tier.
